Be it known that l. HERMAN nin- MAN, a citizen of the llnited States., residingr y. at St. Louis, Mlssouri. have invented a cer- 2' tain new and useful Improvement in l"iref Doors, of which the following is a fnl? clear, and exactv description. enable others skilled in the art to which it appertains to make and use the same.

This invention relates to metallic tire doers such as are used in elevator shafts and for clos-ingr variousl other door openings in buildings.

One object of the invention is to provide a fire-door structure that comprises only a few parts which are of such design that the door and the guides for the door can be installed easily.

Another object is to provide a tire-door composed of a plurality of sections, andy sc otlons substantially g closed, thus producmeans for holdingr said rigid when the door is ing a sectional door which is practically as etlicient. as a one-piece fire-door.

Another object is to provide a fire-door structure in which the housings for sonic of thc sheaves of the door-operating mechahism are carried by the vertically disposed tracks or guides on .vhich the door travels. and some of the other sheaves are connected to the upper section of the door. And still another object is to provide a fire-door structure in which the sections of the door are provided at their side edges `fith devices of novel construction that cooperate with stationary tracks of novel design which hold and guide the door vertically.

Other objects and desirable features of my invention will he hereinafter pointed out.

leterrixn;r to thc drawin s which illustrate the preferred form o my invention, and B designate the upper and lower secytions of a horizontally divided fire-door, each of said sections preferably consisting fot' a rectangular-shaped frame 1 formed from pieces of angle-iron, and panels 2 of corrugated metal connected to thevlegs of said angles which form the front face of the frame. Said door is guided vertically hy means of tracks which cooperate with i laterally projecting devices on the side edges of the upper and lower sections of the door. In the preferred form of my invention, as l herein shown, each of said vertically disl pcsed tracks or guides consists of an angle i 3 connected in any suitable manner to the I wall of the building in which the door openf and a channel-shaped meniing is formed,

the flange her 4 Whose weh is connected to f or leg of the angle 3 that projects laterali away from the wa l, each leg or flange 0i ,the channel 4 acting as a`track that col operates with one section of the door. The upper section A of the door is provided at its side edges with laterally projecting flanges 5 preferably formed from pieces of angle-iron which lie between the wall of the building and the front legs or flanges cf the channels 4 thaty form part of the l vertical guides or tracks for the door. .In l addition to the flanges 5 the upper section A of the door is provided with rollers G. as i shown in Fig. 2, that lie on the opposite l side of the front legs of the channels 4 with l l l and projecting door although they could. of

tion A of the departing from the spirit of my invention. i The lower section l' ofthe door is provided y with similar flanges 5a Aand rollers 6a that eznlnace the rear legs or flanges of the chanl nels -i of the vertical tracks or guides. It [will thus he seen that separate tracks or l guides are provided for each section of he l door. and thaty each of said sections is provided at its side edges with a pair of laterlkally projecting.r devices that embrace or lie on opposite sides of the track with which l theliv cooperate, thus holding the .side edges tional View ofl a fire-door constructed in acg course. he arranged in other Ways without of the door securely in position. Furthermore. door of this construction will move freely and can thus be opened easily because it comprises Vhorizontally disposed rolle'rs which travel on the vertical tracks or guides for the door. In the embodiment of my invention herein sho-wn the upper and lower .ends of the laterally projecting flanges 5 vided means for drawing the sections of thel door together and for holding the top and bottom edges of the upper and lower sections, respectively. securely in position when the door is closed. Said means preferably consists of a plurality of angleshaped devices 8 connected to the lintel 9 at the top of the door opening and cooperating with the top cross-piece of the frame 1 of the upper section A ot the door, similar angleshaped devices 8a connected to the lower edge portion of the upper section A of the dooigand cooperating with the top crosspiece ot the frame 1 of the lower section B of the door, and devices 8 preferably of tapered or wedge-shaped':tornnon the bottom edge of the lower section B ot' the door thatenter openings 10 formed in the sillplate 11 that extends across the bottom of the door opening in the wall of the building. As shown in Figs. 1, 2 and 3. the upper scc tion A ot the door is provided with substantially channel-shaped housings or guideways 12 into which the devices 8 on the lintel 'iroject, and the lower section B of the door is provided with similar ehannel- .shaped housings or guideways 12b that receive the devices 9a on the lower edge of the upper section of the door. YVheii the door is closed, or when the sections of the door are moved downwardly the vertical legs of the binding devices 8 on the lintel will strike against the depending flange-ot' the top cross-piece ot the traineot the upper section A and thus draw the upper section ot the door toward the wall ol the building. Likewise, when the lower section B of the door approaches, its normal position the depending tiangc ot the top cross-piece of the trame thereot strikes against the vertical legs of the binding devices S, thereby causing the upper and lower sections of, the door to be drawn together, the tapered or wedgeshaped members 8" on the bottom of tbe loo-er portion B of the door entering the openings in the sill-plate and thus holding Asection A of the door.

swaying or moving away from the wall of the building in case the door is subjected to pressure. ihile I have stated thatl the binding devices 8 on the lintel operate to draw the upper edge of the door toward the lintel and that the binding devices 8a on the lower edge of the upper section Aoi the door operate to draw the two sections of the door together, it is not necessary that said devices 8 and 8a be so adjusted that they have a positive bearing on the depending flanges on the. sections of the door with which they cooperate for said devices can be set in such a manner that they merely act as keepers or stops for preventing the upper edge of the door from springing away from the lintel or the two sections of the door from springing apart in case they are subjected to pressure. i

r1`he two sections of the door are counter- `balanced by means of weights connected to ytion B ot' the door travels upwardly at approximately twice the speed of the upper t'orm of my invention as herein shown, housings 13 are connected to the upper ends of the vertical` tracks or guides for the door so as to support sheaves or pulleys 14'and vent the weights from moving relatively toV the chains. Said chains pass from the weights 18 upwardly over thevpulleys 14 on the housings' 13 and thence downwardly to channel-shaped members 1f) secured to the lower section B of the door, as shown in Fig.'

l.' iVhcn the door is opened the lower, Section B will move upwardly at approximately twiee the speed of the upper section and finally come to rest in a position parallel t0 .said upper section and above the lintel eX- tending across the top ot' the door opening. While l prefer to use two continuous chains In the preferred for operatingr both Set-etionev of the doot; it will` of comme, he ol'wiou` that the Hime restilte` could hc :mcoxnplhhed rato vhaiiw for each door. the haiti-e for the y lower Ser-tion ll being connected :it their lower md5l to the devint-5, lf! on nid lower :fxt'tion und tit their oppfite entiv to the weight# 1h` ond the t'hoiney tot' the upper section ot the door heilig connected :it one end to the :1mm lt on the homing lfl :intl :it their oppmite endol to thi' wei-flaw t9. l prefer to use two continnow chains merely berouw such :i Structure can lie nwtlnililml easily.
